| Abstract: | RRIM - PU had been developed with glass fiber as reinforcement and RIM - PU as matrix.Discuss the effect of RIM - PU raw materials and reinforcement on the processing and material properties of RRIM -PU.The results show that the processing property of RRIM -PU is not only good.with CM -MDI/ PAPI blend and APG being as raw materials and GF length being no more than I.5 mm,but the mechanical properties and thermal stability are excellent,and the properties of RRIM - PU is obviously increased especially than RIM-PU. |
